Astronomers have found what appears to be a gigantic suicidal planet. The odd, fiery planet is so close to its star and so large that it is triggering tremendous plasma tides on the star. Those powerful tides are in turn warping the planet's zippy less-than-a-day orbit around its star. The result: an ever-closer tango of death, with the planet eventually spiraling into the star. It is a slow death. The planet WASP-18b has maybe a million years to live, said planet discoverer Coel Hellier, a professor of astrophysics at Keele University in England. Hellier's report on the suicidal planet is in Thursday's issue of the journal Nature. "It's causing its own destruction by creating these tides," Hellier said. The star is called WASP-18 and the planet is WASP-18b because of the Wide Angle Search for Planets team that found them. The planet circles a star that is in the constellation Phoenix and is about 325 light-years away from Earth, which means it is in Earth's galactic...
